In order for teachers to be able to transform the curriculum into a form comprehensible for pupils, they must first understand the curriculum in depth themselves, the goals, the structures of the curriculum and the relationships within it (Skalková, 2007).
They ask themselves questions such as: What knowledge (definitions, data, rules, realities, etc.) should the student acquire in the given topic in order to acquire a certain level of knowledge? What activities must be included in the lesson, so that the pupil achieves certain desirable skills in the intellectual, motor or psychomotor area by performing them repeatedly? What logical operations and cognitive processes teach the student to think and look for solutions and procedures in the new curriculum? What educational moments does the topic offer? etc.
Conceptual DAC - analysis of key concepts in the topic and the relationships between them. The tool can be a concept map or an analysis of the structure of the curriculum in three categories - facts, concepts and generalizations. Everything is explained in detail in the publication Pasch et al. (1998, ch. 2.2).
FACTS are information about individual facts, they capture phenomena by describing the form, number, position, place, time, etc. Facts represent an ambition to describe reality as objectively as possible.
Ex. Tidal phenomena include ebb and flow, which we can observe at the sea as a regular rise and fall of its level. The tides are caused by the gravitational effect of the Moon (and to a lesser extent the Sun) on seawater.
CONCEPTS are categories or classes of things or ideas with the most important properties in common; it is a generalization of partial facts; they can be concrete or abstract.
Ex. gravity, tides, tides
GENERALIZATIONS are statements that express relationships between two or more concepts, it can be, for example, laws, principles or theories.
Ex. The gravitational attraction between two bodies weakens as their distance increases.
Operational DAC - activities (operations, activities) of pupils in the lesson, which lead to the achievement of the learning objectives. Each activity is prompted by well-thought-out learning tasks. Learning tasks are all tasks assigned by the teacher, respecting the learning goal: a) tasks, b) questions, c) application tasks.
